Marine scientists confirmed over the weekend that a dead fin whale found on a Bolinas shore last week died because it was hit by a ship.
It's the third whale in the Bay Area found to have died due to human causes in the past month, researchers at the Marine Mammal Center and the California Academy of Sciences said.
Barbie Halaska, a researcher for the Marine Mammal Center, said the fin whale is endangered.
"Nobody wants to hit these guys," Halaska said. "I mean, they're amazing creatures, and it's all accidents. It's just that we're all using the same ocean and we need to figure out how we can all use this ocean together and all survive from it."
Researchers say ship strikes and entanglement in fishing gear are the leading causes of whale mortality, especially during migration periods.
